CARTER, OF. JOHNSON CITY, TENNESSEE, ASSIGNOR T0 AmICAN GLANZ- STOFF CORPORATION, OF NEW YORK, N. Y., A. CORPORATION 0F DELAWARE FLANGED SPOOL AND HOLDER THEREFOR In the manufacture of artificial laments, especiallyby the wet spinningprocess, the filaments are wound directly upon spools. While upon ,these spools the filaments are usually wet treated either by the vacuum or pressure washing system and dried.

One object of the present invention is to provide a spool and holder therefor which may be used in the process noted above.

Another object of the present invention is to provide a spool on which filaments may be spun, the circumference of which may be incremented, before the laments are wound thereupon, and the circumference of which may be lessened before the Wet treating and drying steps.

Another object of the present invention is to provide a spool of the type set forth which will aid in theproduction of evenly shrunk and name-free yarn. When certain yarns are` made up into fabrics, and dyed, a series of stripes called the flame or zebra elfect results. When these objections are notpres-` ent, the yarn is said to be flame free.

Other objects will become apparent from a study of .the following specification and of the accompanying drawings, in which Fig. 1 is a longitudinal cross sectional view of the spool and holder;

y Fig. 2 is a sectional view taken on the lines 2-2 of Fig, 1, and showing the blades of the spool holder in outward position;

Fig. 3 is a view similar to Fig. 2 showing the blades in retracted position;

Fig. 4 is a side elevational view in cross section of the spool itself. j l Fig. 5 is an end view of the spool;

Fig. 6 is a perspective view of one of the blades to be used; and,

Figs. 7 and 8 are segmental views of modiiicatmns.

As shown in Fig. 1, a spool is composed of an outer perforated and slotted shell or tube 1 and two end portions 2 2. These end portions are provided with outwardly extending Hanges 3, these flanges being provided with recesses or openings, 4. The spool is slotted in a plurality of placesas at 5, eight slots being shown in the drawings. It is to Ibe un-4 derstood, however, that it isV not wished that the present invention be limited to eight slots,

and that the use of eight slots here is merely l illustrative. The slots 5 extend the `full length of the spool and terminate only within a portion of the flanges 3, as is clearly shown by Fig. 4. These anges 3 are provided with tapered or curved faces 6, theutility of which will be brought' out later.

These flanges 3 may be gripped on the spool porting the blades are shown in Fig. 1. This older comprises a base section 9, secured, for example, by a nut 10, to the spindle portion 11 of the machine. A core 12 may be moved inwardlyv or outwardly-by manipulation of a knob 13.` rlhis core portion is provided with tapered faces 14: and 15, and a cylindrical portion 16. The blade 17 has rounded outer edgesto prevent damage to yarn rspun thereon 18 and shoulders or sto s 19 which prevent it from passing entire y through the slot 5. The outer face of the blade is tapered at 11 and 15', straight at 16v, and it will be noted that 14', 15' andl correspond exactly to the tapered faces and the straight edge of the core, 14, 15, and 16. As shown in the drawings, when the knob 13 is pulled outwardly the-tapered and straight edge portions 14, 15 and 16 are no longer inA contact with the faces 14:, 15' and 16. When the knob 13 is pressed inwardly, a given distance, the tapered portions come in contact with one another f lt is thus seen that by ressing the knob still further inwardl the iilades will all be allowed to contactwit the tapered faces of the core and thus will recede through the slots. 'lhese blades are each rovided with an L-shaped slot 20 which orms a projection 21. An elastic means 22 100 y spool.

is provided and engages the projection 21 of each of the blades 17. |lhis shows that the elastic means 22 tends to hold the blades downwardly or in Contact against the core at all times. ln operation, the knob 13 is pressed inwardly and the elastic means 22 tends to hold the blades closely against the core 12. vln this position the core faces 14, 15 and 16 will be in Contact with the blade faces 14', 15 and 16. The spool is placed ever the holder and rotated until the slots 5 coineide in position with the portion of the blades 17. The knob 13 is then pulled outwardly and as the faces 14 and 15 pass outwardly from the faces 14 and 15', the blades 17 will be forced through the slots 5 and will be held in l,that position owing to the fact that the tapered part of core passes the tapered face of the blade a certain extent. The lilaments 23 are then wound upon the surfaces 18 thus provided.

1t will be noted, as is clearly shown in Fig. 2, that the filament body builds up here, in the shape of an Octagon, so that the filaments themselves do not come in contact with the face 1 of the spool. 0f course if six blades are used, the shape of the thread build will be a hexagon, etc. A filament body slightly deeper than the depth of the groove 4 and the flange 3is usually Wound upon the spool. The thread guide used is adapted to make a stroke which is slightly longer than the spool surface between the flanges and thus lay the yarn snugly'against said ilanges. The tapered portions 6 of the flange 3 act to prevent mutilation of the filaments, and also, when the blades are retracted, the surfaces 6 act to hold the yarn body concentric on the After the yarn body is wound, the knob 13 is pushed inwardly and the elastic 22 causes the blades to recede and resume a retracted position. The spool may then be removed from the holder.

The filaments on the spool is then a self supporting mass similar to a pot spun cake around the spool body and coverthe same to a depth just exceeding the depth of the grooves 4 in the flanges 3. It will thus be seen that in the event the vacuum washing system is used, there will not be a tendency ortheliquid to flow through the groove 4 rather than through the filaments 23. The fila-ments, therefore, are allowed to shrink evenly during the treating and drying processes so thaty a more even shrinkage 1s produced. This production of a more even shrinkage serves to preclude to a greater or lesser extent the production of filaments which possesses flame effects and tends towards the production of filaments with more even drying qualities.

The method of operating the knob 13 may of course be changed, by arrangement of the taperin face portions, so that it will cause the bla es to be retracted when pulled Out- Laatse@ wardly, rather than when pushed inwardly.

1t is intended that this, and other slight alterations in the structure and operation of the device equivalent to those shown herewith, should be covered, and it is desired that the present invention be limited only by the scope of the appended claims.
